L6599AF

Pin connection

N.C.

high voltage spacer. The pin is not internally connected to isolate the high voltage pin and

ease compliance with safety regulations (creepage distance) on the PCB.

OUT

High-side gate-drive floating ground. Current return for the high-side gate-drive current.

Layout carefully the connection of this pin to avoid too large spikes below ground.

HVG

High-side floating gate-drive output. The driver is capable of 0.3 A min. source and 0.7 A

min. sink peak current to drive the upper MOSFET of the half bridge leg. A resistor internally

connected to pin 14 (OUT) ensures that the pin is not floating during UVLO.

VBOOT

High-side gate-drive floating supply voltage. The bootstrap capacitor connected between

this pin and pin 14 (OUT) is fed by an internal synchronous bootstrap diode driven in-phase

with the low-side gate drive. This patented structure replaces the normally used external

diode.
